CVE-2017-2583 – Kernel: Kvm: vmx/svm potential privilege escalation inside guest
https://notcve.org/view.php?id=CVE-2017-2583
The load_segment_descriptor implementation in arch/x86/kvm/emulate.c in the Linux kernel before 4.9.5 improperly emulates a "MOV SS, NULL selector" instruction, which allows guest OS users to cause a denial of service (guest OS crash) or gain guest OS privileges via a crafted application. La implementación de load_segment_descriptor en arc/x86/kvm/emulate.c en el kernel de Linux en versiones anteriores a 4.9.5 emula indebidamente una instrucción "MOV SS, NULL selector", lo que permite a usuarios del SO invitado provocar una denegación de servicio (caída del SO invitado) u obteniendo privilegios de SO invitado a través de una aplicación manipulada. Linux kernel built with the Kernel-based Virtual Machine (CONFIG_KVM) support was vulnerable to an incorrect segment selector(SS) value error. The error could occur while loading values into the SS register in long mode. A user or process inside a guest could use this flaw to crash the guest, resulting in DoS or potentially escalate their privileges inside the guest. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=33ab91103b3415e12457e3104f0e4517ce12d0f3 http://www.debian.org/security/2017/dsa-3791 http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.9.5 http://www.openwall.com/lists/oss-security/2017/01/19/2 http://www.securityfocus.com/bid/95673 https://access.redhat.com/errata/RHSA-2017:1615 https://access.redhat.com/errata/RHSA-2017:1616 https://bugzilla.redhat.com/show_bug.cgi?id=1414735 https:/ • CWE-250: Execution with Unnecessary Privileges •

The vc4_get_bcl function in drivers/gpu/drm/vc4/vc4_gem.c in the VideoCore DRM driver in the Linux kernel before 4.9.7 does not set an errno value upon certain overflow detections, which allows local users to cause a denial of service (incorrect pointer dereference and OOPS) via inconsistent size values in a VC4_SUBMIT_CL ioctl call. La función vc4_get_bcl en drivers/gpc/drm/vc4/vc4_gem.c en el controlador VideoCore DRM en el kernel de Linux en versiones anteriores a 4.9.7 no establece un valor errno sobre ciertas detecciones de desbordamiento, lo que permite a usuarios locales provocar una denegación de servicio (referencia incorrecta al puntero y OOPS) a través de valores de tamaño inconsistentes en una llamada ioctl VC4_SUBMIT_CL. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=6b8ac63847bc2f958dd93c09edc941a0118992d9 http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.9.7 http://www.openwall.com/lists/oss-security/2017/01/21/7 http://www.securityfocus.com/bid/95765 https://bugzilla.redhat.com/show_bug.cgi?id=1416437 https://github.com/torvalds/linux/commit/6b8ac63847bc2f958dd93c09edc941a0118992d9 https://lkml.org/lkml/2017/1/17/759 • CWE-388: 7PK - Errors •
